The paper deals with the experimental study of heat transfer in FC-72 fluid revulet flowing down the vertical heated foil with the length of 80, width of 35 mm, and thickness of 25 microns, made of constantan. Employing infrared thermography, we have obtained data on temperature distribution on the foil from the opposite side of the rivulet flow. Further we will calculate the heat flux on the foil surface. It is experimentally revealed that the rivulet width reduces with increase in thermal power due to evaporation, while it increases with increasing fluid flow rate. The FC-72 fluid has good wettability and low latent heat of evaporation. Thus this fluid is recommended for use in cooling systems.
